DUMPING-CAR.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Application filed December 1, 1919. Serial No. 341,779,

To all w 7mm it may concern Be it known that I, CARL P. AsTnoM, a citizen of the United States, and resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Dumping Cars, of which the following isa specification.

This invention relates to dumping cars more especially for hot metal and has for its object to provide a short pouring car having simple and effective means for overcoming the body tilting during pouring and to maintain the pouring arc of the ladle short and substantially constant.

According to this invention, a spring supported car body is rigidly blocked during pouring in such manner as to constitute a short pouring rigid structure adaptable for standard cars without requiring special wayside dumping trunnions.

The accompanying drawing shows two forms, which can be varied without departure from the spirit and scope of the appended claims.

In the drawing,

The figure is an end elevation of a car cmbodying the invention, certain parts being indicated in different positions in dotted lines.

5 designates a frame mounted on a suitable truck or trucks 6 traveling on the track-way 7, the truck being of standard railway type with the usual springs, one of which is shown by breaking away the right hand. end of the truck, journal box and axle as viewed in the figure and is designated 32.

8 designates the body provided in the present instance with opposite pouring spouts 9 and 10 and with supporting and pouring trunnions 11 and 12 for the respective spouts. Trunnions 11 and 12 are each disposed laterally of the center line oi the body. These pouring trunnions are supported in bearings 13 and 14- provided on the frame, said bearings being of the open type to permit pouring of the body on either side, and to permit of the removal and replace ment of the ladle, the ladle being shown as provided with the usual lifting trunnions 15 for attachment of the crane hooks.

, The dotted lines show how, when the ladle is to be poured to the right, the pouring trunnion 12 journaling in the bearing 14: operates as a pouring center for the ladle,

and it will be equally clear that when the ladie is tipped to the left, the pouring trunnion 11 will serve as the pouring center, giving as short a pour as desired into the runner at. The body has the usual lugs 3 to receive the crane hooks for dumping, or the body may have dumping gear and be operated by a motor.

It will be evident that when the weight of the filled body is thus shifted to one side, there is a tendency to settle at the pouring side, and further that as the weight is reduced by the pouring of the metal, the springs will have a tendency to react. The preferred means consists of a stationary block or wall 16 at the side of the track-way in combination with an outstanding bolster or bolsters 17 on the frame, arranged to override such stationary support, and a chock or chocks 18 bearing on the stationary support, and adapted to be projected to close the gap between the stationary support and the overhanging bolster. Thechock 18 may be of wedge shape, as indicated, and the under face of the bolster maybe correspondingly inclined.

Ordinarily, the car will be provided with two such bolsters, one at each end and a corresponding number of chooks will be provided. Also, preferably the choclrs at the opposite ends of the car will be simultaneously operated, for instance, from a pivoted rock shaft 19 having rock arms 20 connected by links 21 withthe respective choclzs. This rock shaft is shown as operated by a hand lever 22- connected with the rock shaft by an elbow lever 23, link 24 and rock arm 25.

The operating lever has a weight 26 which causes it to stand in either one of the positions 1I1Cl1CEtt8Cl, thatis, with the chocks either 111 PI'OJBCtGCl posltlon, or in the retracted position indicated in dotted lines.

In the operation ofthe apparatus, the car is run to the pouring position, the chocks at this time being retracted so that the out standing bolsters clear the support at the side of the track. When the semis properly located the hand lever is swung to the left and the chocks are thereby brought into engagement beneath the bolsters. In this relation oi the parts, the weight is taken oii the springs during the pouring operation so that the bearings for the pouring trunnions are supported by a fixed support at the side of the track.

. This results in the pouring center being maintained substantially fixed, producing a substantially constant and short pouring are. When the pouring is finished and the body is swung back into the position of rest, the springs react to such an extent as to cause the bol 100 tons or more, wherein a short and con stant pour is desired to avoid splashingand waste of metal, as in the runners of casting pits or machines, and where speed is necessary in order to avoid freezing in the body. Vith this invention the spout can go very close to the runner, and the last of the metal will discharge at practically the same spot as the first, giving what is called a short pour with good speed. The invent-ion can be used in various other forms of cars where accurate dumping is desired of materials other than hot metal.

hat I claim is:

1. In a dumping car, the combination with a body provided with a trunnion, of a frame provided with a bearing for said. trunnion, and means external to said frame and positioned on the dumping side for holding said bearing to maintain the same substantially immovable during the dumping operation. 2. In a dumping car, the combination with a body provided with a trunnion, of a spring supported frame having a bearing for said trunnion, of means positioned on the dumping side for holding said frame substantially immovable during the dumping operation. V

3. In a dumping car, the combination with a body provided with a trunnion, of a spring supported frame having a bearing for said trunnion, and means positioned. on the dumping side for supporting said frame againstv swaying movement during the dumping operation.

4. In a dumping car, the combination with a body provided with a trunnion, of a frame provided with a spring supported bearing for said trunnion, and means positioned on the dumping side for holding said spring supported bearing substantially immovable during the dumping operation.

5. In a dumping car, the combination with frame provided with bearings and with a bolster, of a body having a trunnion journaled in said bearings, and supporting means positioned on the dumping'side e11- gageable with the bolster during dumping of the body.

6. In a dumping car, the combination with a spring supported frame and a body having a trunnion journaled in said frame, of means positioned on the dumping side for securing the frame during the dumping operation to maintain the pouring center of he body substantially fixed.

7. In a dumping car, a frame provided with a bearing and with a bolster, a body having a trunnion journaled in said bearint;7 and means positioned on the dumping side engageable with the bolster for supporting the frame during the dumping op eration.

8. In a car dumping apparatus, the combination with a support, of a car frame having a bolster, means engageable between the support and the bolster to support the frame on the dumping side, and a dumping body mounted onthe frame.

I
